bitcoin-core running locally
port 8333 is default port … has been running several months without issues
set dfx.json to port above
fails on:
basic_bitcoin % dfx deploy basic_bitcoin --argument ‘(variant { Regtest })’
console log is here
then added command
cargo add secp256k1-sys
been hanging on nostr with our BTCmaxi brothers and what to show this off 
error occurred: Failed to find tool. Is clang installed?
Sounds like a problem with your machine’s setup to me. Can you make sure that clang is available?

this is where things derail

It’s pretty common to have rust canisters be too big. There’s a few things you can try. Probably easiest is cargo install ic-wasm, which will try to remove unused code from the wasm before uploading. Next is to gzip the wasm before uploading it. This requires a custom build script and you should be able to find more info about it in this or this thread.
thanks got things working by compressing wasm and rolling back dfx 12.1. → dfx 12.0
i was not able to install ic-wasm
some issues may be from using a M1 mac
